var Number=document.getelementbyid (' number '). Value;
var Qq=document.getelementbyid (' QQ '). Value;
var tr=document.createelement (' tr ');
Tr.innerhtml= "<td>" +name+ "</td>" +
"<td>" +number+ "</td>" +
"<td>" +qq+ "</td>" +
"<td><a href= ' javascript:void (0); ' > Delete </a></td> ";

var a=tr.getelementsbytagname ("a") [0];
a.href= ' javascript:void (0) ';
A.onclick=function () {
var r=confirm (' confirm delete ');
if (r) {
Delete
Get click
var Tr=this.parentnode.parentnode;
Tbody.removechild (TR);
}

var nametext=document.createtextnode (name);
var numbertext=document.createtextnode (number);
var qqtext=document.createtextnode (QQ);
var atext=document.createtextnode ("delete");


Put the text in the appropriate TD
Nametd.appendchild (Nametext);
Numbertd.appendchild (Numbertext);
Qqtd.appendchild (Qqtext);

Atd.appendchild (a);


Add TD to TR
Tr.appendchild (NAMETD);
Tr.appendchild (NUMBERTD);
Tr.appendchild (QQTD);
Tr.appendchild (ATD);

var Tbody=document.getelementbyid (' tbody ');
Tbody.appendchild (TR);


}



var Tbody=document.getelementbyid (' tbody ');
var links=document.getelementsbytagname (' a ');

links.href= ' javascript:void (0) ';
var len=links.length;
for (Var i=0;i<len;i++) {
var link=links[i];

Link.onclick=function () {
Prompts the user whether to delete
var r=confirm (' confirm delete ');
